OBJECTIVE To evaluate conduction abnormalities in the nerves innervating the proximal muscles in demyelinating neuropathies (DN) using cervical magnetic stimulation. METHODS We applied cervical root magnetic stimulation in the biceps brachii muscles and examined its activity-dependent conduction changes produced by maximal voluntary contraction (MVC) in 12 DN patients (seven chronic inflammat...

Ulcerative colitis is an inflammatory bowel disease (IBD) characterized by recurrent episodes of colonic inflammation and tissue degeneration in human or animal models. The contractile force generated by the smooth muscle is significantly attenuated, resulting in altered motility leading to diarrhea or constipation in IBD. The aim of this study is to clarify the altered contractility of circula...

we introduce a new concept of general $g$-$eta$-monotone operator generalizing the general $(h,eta)$-monotone operator cite{arvar2, arvar1}, general $h-$ monotone operator cite{xiahuang} in banach spaces, and also generalizing $g$-$eta$-monotone operator cite{zhang}, $(a, eta)$-monotone operator cite{verma2}, $a$-monotone operator cite{verma0}, $(h, eta)$-monotone operator cite{fanghuang}...

background: osteoporosis is a chronic disease that contributes substantially to decrease physical activity and decline in the quality of life. osteoporosis can be diagnosed easily with the use of dual-energy x-ray absorptiometry (dxa) equipment. the aim of this study was to investigate the magnitude of bone loss on proximal femur and lumbar spine ls in pre- and post-menopausal women from isfaha...

introduction: intramedullary nailing (imn) of high tibia fracture has some mechanical and biological advantages over the other form of fixation. however, valgus, apex anterior malalignment and anterior displacement of proximal fragment commonly occur after isolated imn fixation of proximal high tibia fracture. the purpose of this study is to determine the effectiveness of using 3.5-mm locking c...

The human esophagus is composed of striated muscle proximally and of smooth muscle distally with a transition zone between the two. Striated muscle contracts much faster than smooth muscle. The change in pressure over time (dP/d t) of the contraction amplitude should therefore be higher in proximal than in distal esophagus, reflecting the presence of striated muscle proximally. There were 34 no...

BACKGROUND Zone 2 flexor tendon injuries still represent a challenging problem to hand surgeons despite the well developed surgical techniques and suture materials. Meticulous surgical repair with atraumatic handling of the severed tendon stumps and minimal damage to the tendon sheath are particularly important to prevent postoperative adhesions and ruptures in this area.In zone 2 flexor tendon...

1. Chronic alcoholism may be complicated by proximal muscle weakness associated with a selective atrophy of type II skeletal muscle fibres. The histopathological findings are non-specific as identical changes are seen in proximal muscle weakness associated with various metabolic myopathies, including osteomalacia. 2. The maximum voluntary contraction (MVC) of the dominant quadriceps and plasma ...

The offi cial date of the “birth” of the sliding fi lament theory of muscular contraction is May 22, 1954. On this day the journal Nature published two papers consecutively under the general title: “Structural Changes in Muscle During Contraction”. The fi rst paper by Andrew F. Huxley 1 and Dr. Rolf Niedergerke was entitled: “Interference microscopy of living muscle fi bres”. The second paper b...

Approximate proximal point algorithms (abbreviated as APPAs) are classical approaches for convex optimization problems and monotone variational inequalities. To solve the subproblems of these algorithms, the projection method takes the iteration in form of uk+1 = PΩ[u − αkd]. Interestingly, many of them can be paired such that ũk = PΩ[u − βkF (vk)] = PΩ[ũ − (d2 − Gd1)], where inf{βk} > 0 and G ...
